|Pretty much the finished state of affairs now....|
|"Beefy" best describes the Extraterrestrial tire.|
The tread, an inverted style, has a chevron type of a look to it and the negative spaces are textured to add a bit more grip in looser terrain. These tires are not lightweight, XC racer boy treads. The weight on my scale was 930/940 grams each. Or in other words, there are fat bike tires that weigh in this range. Surly isn't known for XC, weight-weenie stuff, so no surprises here. Beefy, durable, reliable- yes. Well, at least one would hope these tires would follow in the footsteps of Surly's past efforts.
Okay, so now about their tubelessness, which was a big deal for me. I mounted the first bead on the Cliffhangar rim with great difficulty by hand. The second bead....no way. I had to lever it on with my Maxxis tire lever. Tight? Oh yeah! I actually used a tire lever to mount both beads of the second tire, as my hands were roached after doing the first bead by hand. Tossed in a little of this Velowurks sealant, which is good to -30°F, and pumped up both tires with a floor pump. Easy. No drama in setting these up at all.
|The Cliffhangar rim and Surly Extraterrestrial tire work perfect as a tubeless combo.|
The Cliffhanger rims really matched up well here and I feel like I should be able to run whatever pressures I want with no fear of burping the tires. I will only say that if I had a disc brake bike I definitely would have opted for the Velocity Dually 26"er rim, as I feel that would have added the capability to go to insanely low pressures for slippery Winter riding and the tires would have had great sidewall support. Imagine that set up on a Big Dummy. Oh yeah!
That said, I couldn't be happier so far with how this has come out, The tires are 61mm wide at the widest point, and my fenders are just shy of that, but they seem to do okay with the big tires anyway. The Cliffhanger rims make the tread area really arch up into a pronounced "C" shape profile, so I have great turn in on corners and the tire rides up on its central part of the tread at anything over 20 psi. Under that, things get cushier and more traction action is happening. The Cliffhanger rims, at 30mm outer dimension width, are probably the widest tubeless rim brake track rims out there for this sort of bike, and their quality is outstanding. With the fit these rims have with these tires, you'd almost swear that they were designed for each other. It really is quite a remarkable set up.
|Lower than 20psi pressures really plant the tread down where you need it when things get slippery.|
It is pretty surprising that an old, simple dog like a cantilever brake 1X1 could be such a blast and so useful, but there ya go. Bicycles are awesome no matter the wheel size, if they have been designed well and set up with carefully considered, quality components. I look forward to thrashing some urban rides and maybe even some mountain biking come spring. In the meantime, look for long term 1X1 updates in the coming months as I use the Project 1X1 as a commuter rig, errand bike, and more.
Thank You: Velocity USA for the rims, tape, spokes, and nipples. Thanks to Surly Bikes for an awesome tire, and making it tubeless, that was great of you guys and gals. Velo Orange for the super smooth hubs. Finally- thanks to all six previous owners of this frame/fork for keeping the circle unbroken.
